The study's objective is to assess the adherence of in different types of denture polymers and the effectiveness of eugenol and commercialized denture cleansers in the removal of . Three types of denture base polymers (Lucitone 199 (High-Impact PMMA), Impact (conventional PMMA) and Eclipse (UDMA)) and two hard denture reline materials (Kooliner and Tokuyama Rebase II Fast) were used in this study.
Three hundred samples were prepared (6 × 2 mm disc shape) and divided into five groups of denture polymers ( = 60) and further subjected into five treatment groups (Polident, Steradent, distilled water, eugenol 5-minutes, and eugenol 10-min). Three samples were extracted from each treatment group for baseline data ( = 12). Baseline data were used to calculate the initial number of adherence. A 0.5 ml immersion solution from each specimen was cultured on YPD agar and incubated for 48 h at 37 °C. Visible colonies were counted using a colony counter machine (ROCKER Galaxy 230).
The result showed that the denture base polymer significantly affected the initial adherence ( = 0.007). The removal of was also considerably affected by the denture base polymers and denture cleansers ( < 0.05). Lucitone, Tokuyama, and Kooliner denture base polymers immersed for 3 min in eugenol showed the best results of removal.
This study's overall results showed that all denture polymers used as denture bases had an effect on initial adherence and removal from the denture base, and eugenol is comparable to commercialised denture cleansers in reducing the number of attached on denture base polymers.
本研究旨在评估不同类型义齿聚合物中 的黏附情况，以及丁香酚和商业化义齿清洁剂去除 的效果。本研究使用了三种义齿基托聚合物（Lucitone 199（高冲击 PMMA）、Impact（常规 PMMA）和 Eclipse（UDMA））和两种硬质义齿衬垫材料（Kooliner 和 Tokuyama Rebase II Fast）。
制备了 300 个样本（6×2mm 圆盘形状），并分为五组义齿聚合物（每组 60 个），然后进一步分为五组处理组（Polident、Steradent、蒸馏水、5 分钟丁香酚和 10 分钟丁香酚）。从每组处理组中提取三个样本用于基线数据（每组 12 个）。基线数据用于计算初始 的黏附数量。从每个样本中取出 0.5ml 浸出液，接种于 YPD 琼脂上，并在 37°C 下孵育 48 小时。使用菌落计数器机器（ROCKER Galaxy 230）计数可见菌落。
结果表明，义齿基托聚合物显著影响初始黏附（=0.007）。义齿基托聚合物和义齿清洁剂对 的去除也有显著影响（<0.05）。在丁香酚中浸泡 3 分钟的 Lucitone、Tokuyama 和 Kooliner 义齿基托聚合物显示出最佳的去除效果。
本研究的总体结果表明，所有用作义齿基托的义齿聚合物都对 的初始黏附和从义齿基托上的去除有影响，丁香酚在减少义齿基托聚合物上附着的 数量方面与商业化义齿清洁剂相当。
